EDWIN F. BEUGLER, OF BUFFALO, NEW YORK, ASSIGNOR TO EDWARD B. HOLMES, 0FBUFFALO, NEVJ YORK.

VERTICAL HOOP-DRIVING- MACHINE Specification of Letters Patent.

Patented Dec. 28, 1909.

To all whom 'it may concern:

Be it known that I, EDwiN F. BEUGLER, a citizen of the United States,residing at Buffalo, in the county of Erie and State of New York, haveinvented certain new and useful improvements in Vertical Hoop- DrivingMachines, of which the following is a specification.

This invention relates to that class of machines used in the manufactureof barrels or the like known as vertical machines and is chieflydesigned to be employed for driving hoops on tight-barrels or barrelsadapted to contain liquids.

One of the features of the invention has reference to a screw bar whichis unrotatably attached at its lower end to the driver head and passesthrough a rotatable screw sleeve on the machine frame, whereby theconstruction is simplified and lightened and great strength of structureis obtained at the juncture of the driver head and screw bar and theoperation of the driver head and its component parts is renderedsmoother and easier.

Another feature has reference to a power device for radially shiftingthe driving arms whereby they are shifted powerfully and accurately withgreat despatch and by minimum exertion on the part of the workman.

Another feature has reference to a bottom plate upon which the barrelsare supported which is partially rotated automatically when the hoopdriving mechanism is elevated to prevent the drivers contacting with thehoop at the same points again should it be necessary to lower the hoopdriving mechanism more than once in order to drive the hoops firmly inplace.

The principal objects of the invention are to obtain great strength ofstructure, to vertically operate the hoop driving mechanism smoothly andeasily to provide for radially shifting the driving arms powerfully andaccurately with a minimum of exertion on the part of the operator and toprevent the hoop drivers pressing against the same points on a hoop onsuccessive desc-ents of the hoop driving mechanism.

The invention also relates to certain details of construction, all ofwhich will be fully and clearly hereinafter described and claimed,reference being had to the accompanying drawings in which,-

In referring to the drawings for the details of construction, likenumerals designate like parts.

The frame of the machine consists of a base l, vertical side members 2,and a horizontal top girt 3, which has its ends bolted to the upper endsof the vertical side members 2, see Figs. 1 and 17. A supplementaryframe for supporting one end of the driving shaft is supported from thebase 1, and side members 2, as shown in Figs. 2, 3, 17 and 19. Thisframe has two rearwardly and diagovertical side members 2, and near theupper ends thereof by bolts 6, see Fig. 19, where thesebolts are shownin dotted lines, and project laterally therefrom in a horizontaldirection gradually converging toward each other. The rear ends of theseconverging frame members 4, are connected by a cross bar 7, which has adiagonally extending arm 8, extending from about the middle of its rearside. This arm is preferably formed integral with the bar 7, andterminates ink a bearing 9, in whichl one end of a horizontal drivingshaft 10, is supported.4 The other end. of the driving shaft 10, is.supported in a bearing which is formed in the rear side of the top girt3, see Figs. 3 and 19.

Diagonally extending bars 11, which have their lower' ends bolted to therear'portion of the base 1, support the rear end of the supplementaryframe, the upper ends of these bars being secured to the rear ends ofthe diagonal portions 4, and to the ends of the cross bar 7, by bolts,see Fig. 2.

' Two driving pulleys 12 and 13, are mounted loosely upon the shaft 10,and rotate in opposite directions. Two frictionv clutches 14 and 15, arekeyed to the shaft, one clutch being placed' adj aeent to' each of thepulleys 12l and 13, see Figs. 3 and 19. The hubs 16 and 17, of thepulleys are elongated and eX- tend toward each other and each of thehubs is provided with an annular groove in each of which an annularflange 18, extending from a split collar 19, is snugly fitted. The

collar 19 is made in two halves and has opposed flanges 20, throughwhich bolts are passed to secure the two halves together and around thehubs 16 and 17. The collar 19,

is shifted to bring either of the pulleys 12,

or 13, into engagement with its adjacent friction clutch by apivotedyoke 21, which has twov vertically extending arms 22, see Fig. 28. Thesearms constitute a fork which straddles the split collar 19, the upperends of the arms 22, fitting snugly in depressions or notches which areformed in the outer edge ofthe flanges 20. j

The yoke 21, is provided with two depending portions 23, the ends ofwhich extend atright angles and are tapered as shown in Fig. 28. Thesetapered ends serve as pivots upon which the yoke rocks, and aresupported in bearing plates 24, which are adjustably secured to the topsurface of the supplementary frame by bolts, see Figs. 19 and 28. arm25, formed integral therewith, said arm being connected at its forwardend by a link 26, to the rear end' of a lever 27, which is The yoke 21,has an angularV fulcrumed on a pin 28, extending` from the side of thesupplementary frame, see Figs. 2, 19 and 28. The other end of the lever27, is pivoted to the upper end of a vertically extending rod 29, thelower end of which is screwed into a forked block 30. This forked block30, is pivoted to the rear end of a horizontal lever 31, which isfulcrumed on a pin extending from one of the side frame members 2. Theforward end of this lever 31, is enlarged and is provided with a curvedslot 32. The rear end of a diagonally eX- tending handle 33, is fastenedby a bolt to the enlarged portion of the lever 31, and another bolt 34,passes through the handle 33, and the curved slot 32. A portion of theouter surface of the enlarged end of the lever 31, is roughened orserrated as shown in Fig. 41, and the handle 33, is similarly roughenedupon its inner surface so that when the bolt 34, is tightened thehandle-33 and lever 31, are locked tightly together. By loosening thenuts upon the bolts the handle may be adjusted to various heights.

rllhe lever 31, has two forked depending lugs 35, and a cross bar 36,which is fastened to the upper end of a vertical stem 37, fits betweenthese forked lugs. The lower end of the stem passes loosely through anopening in the horizontal portion of an angle plate 38, which is boltedto the side member 2. A spiral spring 39, encircles the stem between theplate 38, and the cross bar 36, and serves to normally maintain thelever 31, in a horizontal position.

rl`he hoop driving mechanism is supported between the vertical sideframe members 2, so as to be capable of a vertical up and down movement,and is illustrated in Figs. 1, 2, and 3, and Figs. 22 to 27 inclusive.

The driving head is preferably in the form of a spider as shown in Figs.1, 3, 22, 23 and 34, and has a central hub 40, which is reduced at itsupper end, see Fig. 23. A series of radial ribs oi arms 41, extend fromthis central hub, and connect at their' outer ends with an annularseries of equally spaced blocks 42, which are provided with verticalslots 43. A circular rim 44, connects these blocks with each other andto a horizontal bottom portion 45, which extends from the bottom of thecentral hub to the rim 44. The hub 40, arms 41, blocks 42, rim 44, andhori zontal bottom portion 45, are all made in one integral piece asshown in Figs. 22, 23

and 34.

rlhe driving head is provided with two forked portions 46, which areplaced oppositely to each other and are formed integral with the head.rl`hese forked portions constitute guides in which slideways 47,extending from the inner side of each side frame inember 2, fit. rlieforked portions or guides 46, extend above the head so as to provide acomparatively long bearing for the slideways, see Fig. 1. The drivinghead is securely fastened to the lower end of the vertical screw bar 48,which has a comparatively heavy and coarse screw thread Cut thereon forthe greater part of its length, and which supported by a `revoluble nut49, see Fig. The lower end of the screw bar 48, is slightly reduced indiameter and is fit-ted into a vertical opening in the hub 40, of thedriving head. The eXtreme lower end of the screw bar 48, is providedwith a screw thread and a nut 50, which is seated in a depression formedin the bottom of the hub 40, is screwed upon the lower end of the screwbar 48, and securely fastens the driving head to the screw bar. Keys aredriven into the bar 48, and the lower portion of the hub 40, and preventany rotating movement of the bar in said hub, see Figs. 3 and 23.

The drivers are equal in number to the number of blocks 42, and eachdriver is secured to the lower ends of a pair of driving arms as shownin Figs. 23,26 and 27. Each pair of driving arms comprises a maindriving arm 51, and a supplementary arm 52, which is shorter in lengththan the main driving arm 51, and extends parallel therewith. Each maindriving arm 51, extends through one of the slots 43, in the blocks 42,to which it is p ivoted by a pin as shown in Fig. 23. 1t will be seen byreferring to the said figure that the pivoting pin of the main drivingarm is placed close to the upper end of said arm.

Each of the blocks 42, has an extension 53, which is provided with avertical slot 54, in which the upper end of the supplementary drivingarm 52, is pivoted by a pin. A triangular shaped block 55, is pivoted bypins to the lower ends of each pair of driving` arms 51 and 52, seeFigs. 23 and 26. By referring to Fig. 23 it will be seen that the to thelower ends of each pair of driving arms 52, are in a lower plane thanthat of the pivoting pins of the main driving arm, and it will also beseen that the distance between the centers of the upper and lowerpivoting pins of the supplementary driving arm is exactly equal to thedistance between the centers of the upper and lower pivoting pins of themain driving arm.

Flach triangular block 55, has one of its edges curved and a depressionis formed in this curved edge in which the lower ends of the paralleldriving arms 51 and 52 are seated, see Figs. 26 and 27. rlfhe bottomedge of each triangular block is slightly beveled or tapered and arectangular block 56, is secured to said bottom edge by a countersunkscrew 57, see Fig. 27. A guide block 58, is secured to the rectangularblock 56, by a bolt 59, and said guide block is provided with a topdepression in which a driving plate 60, is seated, so that the drivingplate will be interposed between the pression in the top face of therectangular block 56, see Fig. 27. The inner edge of the driving plateis preferably chamfered as shown in Figs. 23 and 27, and extendsslightly beyond the guide block 58, so as to fit over and grip the hoop.

The upper ends of the main driving arms 51,. extend beyond the blocks42, and are connected to a shiftable collar 61, by means of angularconnecting links 62. This shiftable collar is fitted' around the reducedupper end of the hub 40, of the driving head and is supported upon theshoulder which is formed by reducing' the end of the hub, see Fig. 23.The shiftable collar 61, has a horizontally extending flange formedintegral therewith, and an annular series of vertical pins 63, extendfrom the flange, alternately from its top and bottom. surfaces, see Fig.25.

The inner ends of the angular connecting links 62, have openings inwhich the pins 63, lit, and their outer ends are enlarged and providedwith pockets in which the upperY ends of the main driving arms 51, areseated. The links are held in place by pins which pass through the maindriving arms and through slots in the connecting links, see Figs. 1, 2and 3. A spiral spring 64, is seated in the pocket of each connectingline 62, and bears outwardly againstthe main driving arm, see Fig. 23.The arm 51, has a slight movement against the spring 64,` as theconnecting pin has a slight longitudinal movement in the slots in theconnecting link.

The screw bar 48, and the driving head are given a verticalreciprocating movement by the revoluble nut 49, which is mounted on ballbearings in the top girt 3, see Figs.

- 3, 17 and 19. The top girt 3, has a central depending portion 65,which is provided with a cent-ral vertical opening. The revolving nut49, is in the form of a comparatively long sleeve and has a heavyperipheral flange or enlargement 66, at its lower end. This flange 66,has a comparatively deep annular groove formed in its top surface, andthe outer wall of this groove has a lining in the form of a ring 67, ofhardened 'metal such as steel, which is fitted tightly in place. Aheavier ring 68, of similar metal is placed in the bottom of the annulargroove and a series of hardened metal balls 69, are placed upon the ring68. A ring 70, which is similar to the ring 68, is placed upon the balls69, as shown in Fig. 18, and these rings 67, 68 and 70, and the balls69, constitute the lower ball bearing.

The upper end of the revoluble nut 49, extends above the top surface ofthe top girt 3, and a large bevel gear wheel. 71, has a central hubwhich is provided with an opening through which the upper end ofl thenutv 49, extends, see Fig. 17. The gear wheel 71, is securely fastenedin place by a` key as shown in Fig. 3. The lower end of the hub of thebevel gear 71 is reduced andv a thin washer 72, of hardened metal isplaced against the shoulder formed by reducing the hub. A ring 73, ofhardened metal` is placed around the reduced portion of the hub and uponthe washer 72. A similar ring 74, is placed upon the top surface of thetop girt 3, directly beneath the ring 73, and a series of hardened metalballs 7 5, are interposed between the rings 73 and 74, see Fig. 17. Thisconstitutes the upper ball bearing.

The upper extremity of the nut 49, is exteriorly screw threaded and alock nut 76, formed substantially as shown in Figs. 1, 2, 3, 4 and. 17,is, screwed thereon. This lock nut 76, is split, and is provided withlateralv lugs through which a clamping bolt 77 is passed. The lock nut76, has an an nular upwardly extending flange 78, which forms a well oroil pot 79, in which lubricating material is placed to lubricate thescrew bar 48, see Figs. 3 and 17. Radial lugs 80, are formed on thesplit nut 76, and

are adapted to be grasped by a suitable tool to tighten the lock nut.

An annular upwardly extending flange 81, is formed upon thetop surfaceof the top girt 3, around the upper ball bearing and serves to retainthe lubricating material which lubricates the said bearing. If thebearings should become loose because of the wearing of any of the parts,the clamping bolt 77, is loosened, and the split nut 76, is rotated todraw up the nut 49, until the bear` ings are properly adjustedand thenthe clamping bolt 77, is tightened to lock the spl-it nut 76, in place.The nut 49, is provided with an internal screw thread 82, which engagesthe screw thread on the bar 48. The bevel gear wheel 71- and the nut 49,are revolved by means of a small gear 83, which is mounted on the maindriving shaft 10, and which meshes with the gear wheel 71, see Figs. 2and 3. The collar 61, is shifted or partially rotated by a powermechanism to move the driving arms and drivers toward or from thebarrel. This mechanism is located on the top girt and is illustrated inFigs. 1, 2, 3, 4, 17, '19, 22, 23, 29, 30, 31, 32, 33, 37, 42, and 43. l

A bracket 84, is secured by bolts to the top surface of the top girt 3,and near one end thereof and forms a bearing in which a shorthorizontalAshaft'85, is supported. The ends of this shaft extend beyond thebearings and two oppositely rotating pulleys 86 and 87, are mountedloosely upon the shaft, one at each'end thereof. Twofriction clutches 88and 89, are securely fastened to the extremities of the shaft, one beingladjacent to and adapted to engage with each of the pulleys 86 and 87,see Figs. 2, 4, 19 and 29.

The hubs 90, of the pulleys 86 and 87, are elongated and each hub isprovided with a peripheral groove in which the forked upper end of anarm 91, is adapted to fit. These two arms 91 are fastened by set screwsto a horizontally extending sliding bar 92,

which is slidably mounted in lugs 93, projecting from the bracket 84,see Fig. 29. A block 94, is secured by a set screw to the forward end ofthe sliding bar 92, and has a diagonally extending groove or depressionformed in its bottom surface, see Fig. 33.

A rocking collar 95, is supported upon a pin 96, projecting from thefront of the top girt- 3, and said collar 95, has a vertical extensionor lip 97, which extends diagonally across the collar and the upper endof which is adapted to seat in and operate in the groove, seeFig. 29. Ablock 98, extends diagonally from the lower surface of the collar andhas a pocket formed therein in which the upper end of a hand lever 99,is fitted and secured in place by a set screw.

1t will be seen that by moving the hand lever 99, to the right or to theleft, the collar 95, will be rocked upon the pin 96, and by means of thediagonally placed lip 97, will impart a transverse movement of the block98, and sliding bar 92, and so bring either of lthe pulleys 86 or 87into engagement with its adjacent friction clutch and revolve the shaft85, in either direction at the will of the operator.

A horizontally extending bearing portion 100, projects laterally fromone side of the bracket 84, and has a vertical opening formed therein. Adiagonal gear 101, is

seated upon the bearing 100, and has an4 elongated hub 102, whichprojects through the opening in the bearing. A collar 103, is secured bya set screw to the lower extremity of the hub 102, and prevents anyvertical movement of the diagonal gear 101. This gear meshes with asimilar diagonal gear 104, which is keyed to the shaft 85, see Fig. 19.

A vertical opening 105, which is square in cross section is formed inthe diagonal gear 101, and its hub 102, and a vertically extendingsquare sliding shaft 106, is passed through the opening 105, and isadapted to slide therein. This square shaft 106, passes through anopening 107, in the top girt 3, and has its lower end rounded andsupported in a bearing block 108, which is secured by a bolt to one ofthe forked portions 46, on the driving head, see Fig. 37. A pinion 109,is secured to the lower extremity of the shaft 106, and meshes with asegmental gear 110, which has a split hub .111, see Figs. 22

and 37. This split hub 111, is clamped around the upper end of theshiftable collar 61, by clamping bolts 112.

1t will be seen that the rotation of the shaft 85, will rotate thesquare shaft 106, and by means of the pinion 109, and scg mental gear110, will give the collar 61, a partial rotation, and so by means oftheconnecting link 62, will operate the driving arms.

A collar 113, having a peripheral flange is fastened to the lowerportion of the square shaft 106, and said flange has an annular seriesof vertical openings 114, formed therein in which pins 115, may beplaced, so that they project below the flange, see Fig. 42.

The bearing block 108, has a laterally projecting arm 116, through theouter end of which a bolt 117, is passed. A horizontally extending plate118, is secured to the arm 116, by the bolt, and a spiral spring 119,encircles the bolt and is held in place by a washer and a nut screwedupon the outer end thereof. The plate 118, extends toward the bearingblock 108, and acts as a stop against which the pins 115, strike tolimit the rotative movement of the shaft 106.

A mechanism for turning the barrel end for end is provided and isillustrated in Figs. 1 to 15, inclusive. A bearing block 120, is boltedto each of the diagonal frame bars 11, a short distance above the baseand has V shaped bearing points 121, see Fig. 7, upon which a horizontalrocking bar 122, is supported. The ends of this bar 122, project beyondthe bearings and a block 123, is placed upon the bar outside each of thebearings 120, see Fig. 5. The openings in the blocks 123, through whichthe bar passes are slightly larger than said bar and the blocks are heldin place by cone pointed set screws 124, which bear against the bar 122,and per mit the blocks 123, to have a slight pivotal movement. Anopening 125, is formed in each of the blocks 123, below the openingthrough which the bar 122, passes and said openings 125, extend at rightangles to the upper openings. Two angular lifting bars 126, have theirrear ends passed through the openings 125, in the blocks 123, and havetheir forward ends flattened and provided with laterally extending conepoints 127, see Figs. 3 and 5. rfhe forward ends of the angular bars126, extend forward just. far enough so that the cone points 127, willgrip a barrel a short distance below the center. The rear ends of theangular lifting bars 126, extend beyond the blocks 123, and twodiagonally extending connecting links 128, connect the rear ends of thebar 126, to the upper end of a vertically extending rod 129. This rod129, has its lower end pivoted by a bolt to one end of a horizontallever 130, which is fulcrumed on a bolt passing through a bracket 131,see Fig. 2. The other end of zontal bar 138, is secured by bolts atitsvenient reach of the operator and has a foot' treadle 134, bolted toits forward end. The height of this foot lever 132, can be adjusted bymeans of a slotted stopv block 135, which is adjustably secured to theside frame mem-- ber 2, and has a finger extending over the foot leveras shown in Figs. 2 and? 6. A casting or block 136, is secured to therear end of the foot lever and has a vertical openlng and a slot throughwhich the chain is passed. The chain is drawn up through the opening andthen slipped back into the slot and held there.y l

Each of the bearing blocks 120,7 has a projecting lug or extension 137,and a horiends to these lugs 137. rThis bar has a fork 139, projectingfrom the middle of its rear side, which serves as a guide for thevertical rod 129. The bar 138, also has a forwardly projecting slottedlug 140, which supports an eye bolt to the lower end of which one end ofa spiral spring 141, is fastened. The lower end of the spring 141, isfastened to the bolt which connects the vertical bar 129, and thehorizontal lever 130, see Figs. 1 and 3. The purpose of this spring istoy return the parts of the barrel turning mechanism to their normalpositions after the barrel' has been turned end for end upon the releaseof the foot lever 132.

A block 142, having a hook portion 143, is secured by a set screw to therear portion of each of the angular liftingbars 126, between the blocks123, and the lower ends of the diagonal connecting links 128, so thatthe hook portions 143, extend beyond the ends of the connecting links128, and retain them in place on the angular lifting bars, see Fig. 2.

The height of the front ends of the angular lifting bars 126, may beadjusted so that different sizes of barrels can be operated upon. Thisis done by tilting the horizontal bar 122, in either direction, on the Vshaped bearing points 121, of the blocks 120, and so raising or loweringthe front ends of the angular lifting arms so that barrels of differentsizes may be impe-led at a point just below the center upon the conepoints 127. This is done by a lever 144, which has its rear end fastenedto a block 145, having ahorizontal opening through which one end of thehorizontal bar 122, passes, see Fig. 13. The lever is securedA totheblock by a bolt 146, which extends through the blockl and has its upperend bent over the top edge of the lever. The bolt extends below theblock and is encircled by a spiral spring 147, which is held in place bya washer and esigere 'nut screwed: upon thev lower end ofthe bolt',

see Figs. 13- and 14.

A curved'barv 148, is secured byv bolts to lugsv extending' from theadjacent vertical side member 2, of the machine frame -so-that there isa space between thebar 148, and the member 2, and the bar has a seriesof' radial `depressions 149, formed in its inner surface as shown inFigs. 1 andv 6. The front end of the lever 144, is shaped to form ahandle and has two radial lugs or teeth 150, which fit into thedepressions 149, and hold the lever in any position it may be placedE totilt the horizontal bar 122.

The barrel turning mechanism' operates as follows, When the hoops havebeen driven upon the upper end of the barrel, the operator depresses thefoot lever 132, which draws down the vertical bar 129, by means of thelever130. This spreads the rear ends of the angular lifting bars 126, bymeans of the diagonal connecting links 128, and so brings the front endsof the angular bars 126, against the sides of the barrel and embeddingthe cone points 127, therein. The operator now grasps the handle at theforward end of the lever 144, and lifts saidy lever thereby tilting thehorizontal bar 122 and raising' the barrel. As the barrel is grippedbelow the center by the cone points it will automatically swing on thecone points and turn bottom up. The operator now' returns` the lever14'4, to its former position and-f releases the foot lever, when thespring 141, returns the parts to their former position. The remaininghoops arev now driven uponf the barrel'.

A device is provided for giving the bar# rel a slight rotation at eachupward: movement of the driving mechanism so thatv if the hoop should?not be driven home at the first downward movement of *the`drivingmechanism and a` second pressure upon` thev hoops be necessary,the drivers will not grip the hoops in exactly' the saine place afsbefore` but at a different point and so give amore This equal pressureall aroundy the barrel. mechanism is illustrated in Figs. 1, 2', 3^, 34,a5, a6, as, 391 andi io;

A circular plate 151, has a pin 152, ex-

tending from the middle of its bottomA sur-V face which pin lits in anopening 153, formed in the. middle of the base 1, so that the plate 151,restsl upon the base and is capable of being rotated thereon, see Fig.3'. rFhis plate 151, has an annular' seriesY of ratchet teeth 154,formed in its top surface at its outer edge which are adapted' to beengaged by a pawl 155. This pawl is in the form of a rod, one endl ofwhichv is curved to engagethe teeth 154, and the other end of which isbent to form an eye 156, see Fig. 38. This eye fits over a pin extendingfrom the lower end of the longer arm of a bell crank 157,

Aee

the shorter arm of; which has a pin which extends through anlopening inthe lower end of a long vertically extending bar 158. The bell crank 157is pivoted on a pin 159, extending horizontally from the upper end of avertical arm 160, which is formed integral with a block 161, see Figs.35 and 38. This block 161, is secured in place by two of the bolts whichfasten the vertical side member 2, to the base. The block 161, has twolateral extensions or lugs 162, which serve as stops to limit themovement of the longer arm of the bell crank 157, see Fig. 38. rChe bellcrank 157 is operated to rotate the plate 151, by a friction devicewhich is supported from the driving head.

An arm 163, which is provided with two forks 164 and 165, is secured tothe driving head by a bolt so that the larger fork 164 straddles the bar158. This bar 158, extends upward to about the height of thesupplemental frame as shown in Fig. 2. rlCwo recessed plates 166, aresupported by the fork 164, one -on either side of the bar 158, each ofthe plates having lateral lugs 167, through which bolts 168, are passedto secure the two plates together. Each plate 166, has two recesses onits inner face, the lower and longer recess of each plate having a block169, of friction material such as wood, fitted therein as shown in Fig.40. The upper recess of each plate is filled with wool or waste whichhas been previously saturated with a lubricant. r1`he friction blocks169, engage with the flat faces of the bar 158, and are adapted to gripthe same, being pressed against said bar by spiral springs 170, whichencircle the ends of the bolts 168, see Fig. 40. The gripping power ofthe friction blocks may be varied by tensioning the springs 170.

The lugs 167, support the plates 166, in the fork 164, and lugs 171,extending from each side edge of the plates fit against the bottomsurface of the fork and prevent the friction device from being carriedupward out of the fork, see Fig. 39. The top surface of the fork 164,has two depressions formed therein in which a pin 172, is fitted toretain the friction device in place in the fork, see Figs. 36 and 39.

1t will be seen by the above description and by referring to thedrawings, that as the driving head moves upward after driving a hoopinto place, the friction device above described will grip the bar 158,and carry said bar upward until the longer arm of the bell crank 157,strikes one of the stops 162, or, referring to Fig. 38, from theposition shown in full lines to the position shown in dotted lines. Thismoves the pawl 155, as shownl which-gives the circular plate a partialrotation. Then the bell crank has reached the limit of its movement thefriction -device will slide on the bar 158,

and said bar remains stationary. At the downward movement of the drivingmechanism the bar 158, will move downward and return the bell crank 157,and pawl 155, into the position shown in full lines in Fig. 88, readyfor the neXt stroke.

The friction device is tensioned by the springs 170, so that its gripupon the bar 158, is just strong enough to move the circular plate 151,but will slide upon the Abar when the bell crank reaches the limit ofits movement. The fork 165, of the arm 163, straddles the vertical rod29, and upper and lower collars 173 and 174, are secured by set screwsto the rod above and below the fork 165, see Fig. 2. Spiral springs 175and 176, encircle the rod 29, above the fork 165, and the collar 174,and serve as cushions between the fork 165, and the collars 173 and 174.The driving pulleys 12 and 13, are automatically released from thefriction clutches 14 and 15, by the fork 165, coming into engagementwith the springs 175 and 176, which are stopped by the collars 173 and174, and thus moving the rod 29, either up or down and withdrawing thepulleys as before described.

rihe operation of the machine is as follews,-fi barrel is placed inposition on the rotating plate as shown in Figs. 1, 2 and 3, and thehandle 33, moved by the operator to bring the pulley 12, into engagementwith the friction clutch 14, thus lowering the driving mechanism. Theoperator now moves the lever 99, and closes the drivers around thebarrel, the downward movement of the driving mechanism driving the hoopshome. The lever 99, is now moved in the opposite direction to open thedrivers, and the handle 33, moved to disengage the pulley 12, from thefriction clutch 14, and bring the pulley 13, into engagement with thefriction clutch 15, which raises the driving mechanism. The remaininghoops are driven into place in the same manner as above, and when allthe hoops have been driven upon one end of the barrel it is turned endfor end as before described, and the hoops driven upon the other end ofthe barrel.
